FRU IT-JAR.

SPECIFICATION forming part of Letters Patent No. 57'7,225, dated February 16, 1897. Application filed October 4, 1895. Serial No. 564586. (No model.)

To au whom, it may cowern:

Be it known that I, STEPHEN S. BLACK, a citizen of the United States, residin g at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Irnprovements in Fruit-Jars, of which the following is a specification.

One object of my invention is to provide an improvement in wide-mouthed jars by which the same can be perfectly sealed with greater ease and facility than with j ars heretofore in use.

Another object of my invention is superior Simplicity and econony in Construction.

My invention relates to that form of jar in which the body of the jar is provided at its top with oppositely arranged lugs and in which a cover is arranged to fit on a seat in the mouth of the jar and is provided with a centrally-arranged hub and pivot and a crossbar mounted on the hub and embracing the pivot and having its free ends adapted and arranged to be inserted beneath the lugs. The cross-bar may be rigid and used with cam-luge, or the cross-bar can be resilient and the lugs flat and level on their under or bearing faces. By my invention I provide for the use of a plurality of seats or lugs and two cross-bars.

My invention includes an improvement in the bar, and it also includes the combination by which I make the use of two cross-bars practical and Conveniently and easily fasten them to the cover.

It also includes the improved cover provided with a centrally-arranged flanged pivot and a hub provided with a pivotal offset equal in diameter to the fiange of the pivot, a crossbar having a central opening fitted on the pivotal offset, and a cross-bar formed of a wire bent upon itself to form a link open at one end and having its members bent intermediately and clasped upon the pivot between the other cross-bar and the fiange of the pivot.

It also includes other parts and combinations hereinafter set forth.

The accompanying drawings illustrate ny invention.

Figure l is a fragmental perspective view of a fruit-jar embodying my invention. The jar and cover are shown in partial section. Fig. 2 is a mid-sectional elevation of the jar shown in Fig. l. Fig. a is a plan view of a jar embodying my invention with two crossbars in use. Fig. 4 is a fragmental vertical mid-section on line 4: 4, Fig. 3. Fig. 5 is a view of the resilient-wire cross-bar. Fig. 6 is a view of the sheet-metal cross-bar.

A indicates the glass receptacle or jar proper, which is provided above its cover-seat a with sets of oppositely-arranged inwardlyprojecting lugs a' a" d' CW. The cover-seat is flaring, -and the opening in such seat is preferably narrower than the opening between the lugs, so that the cover B can be easily inserted into the mouth of the jar and brought to fit in said seat. The cover B is provided on its upper side with' a centrallyarranged hub b and with a flanged pivot b'.

O indicates a cross-bar mounted on the hub and embracing the pivot and having its free ends adapted and arranged to be inserted beneathtwo opposite lugs. The cross -bars which are shown are resilient, and the hub is of such height that when the crossbar is mounted upon the hub the free ends of the cross-bar must be depressed in order to bring them into place beneath the oppositely-arranged lugs.

The free ends of the cross-bar are adapted and arranged to be inserted beneath the lugs by depressing such ends through the spaces between the luge, and then rotatin g the crossbar to bring the ends under the lugs. i The cover B is provided with a fiange b and with a cylindrical plug b', which plug is adapted to fit in the narrowcst opening of the mouth of the jar. This opening is surrounded by the plug-engaging annular ledge a, which forms the seat for the cover and a centeringguide for the plug and adapts the mouth of the jar to be practically closed by the plug.

In practice a rubber gasket D is placed upon the fiange b". This rubber gasket should be small enough to require to be stretched in placing it over the plug, so that it will be retained thereon by its own elasticity. b'' indicates an annular bead on the under side of the fiange b" of the cover, arranged to press upon the upper face of the gasket to increase the compression of the gasket between the edge thereof and the ledge and the plug, so as to afford perfect scaling. A bead for conpressing a gasket, however, is not claimed as IOO new 3 but I regard my invention as including the combination of the jar having the ledge a, the cover having the bead to rest above the ledge and also having the plug fitted to the opening of the ledge, and the gasket arranged to be compressed within the space which is inelosed between the plug, the bead, and the ledge. The bead is preferably arranged sufficiently inside the angle between the plug and the rim of the flange to be protected by such flange and plug, so that the bead will not be liable to be broken in case the cover is allowed to fall when it is out of the jar.

The cross-bar may be made in various ways, and I have shown two cross-bars in the drawings.

C indicates my newly-invented resilient cross-bar, which is forned of a wire bent upon itself to form a link open at one end and having its members bent intermediately, as at c c', to form a clasp for the pivot. The ends c" c' of the wire are left free, so that the link can be Conveniently, easily, and quickly opened sufficiently to admit the pivot into the clasping portion. The clasping portion is smaller than the flange, so that when in place the fiange oi' the pivot will hold the cross-bar on the pivot. The cross-bar E is made of re silient sheet metal and has an opening e large enough to fit over the fiange-pivot and smaller than the hub b, so that the cross-bar E can be easily placed over the pivot and upon the hub. The hub is provided with an offset or step b (shown in Fig. 4) to receive the cross-bar E. The cross-bar E is provided with upwardlyprojecting lugs e' to prevent the cross-bar C from coming parallel with the cross-bar E The cross-bar C when in place on the pivot forms afastening which holds the cross-bar E in place on the hub.

The form shown in Figs. 3 and 4, where two cross-bars are used, is designed for large j ars. The ordinary jars and small jars will be sealed with the single cross-bar O.

In practice the covers are prepared for use by stretching on the rubber over the plug and by placing the cross-bars or a cross-bar in place upon the pivot. The cross-bars can be applied at the factory or may be shipped separately and applied by the user, and in practice when the jar is filled with fruit the cover is inserted. The ends of the cross-bar are then depressed, and the cross-bar is rotated to bring its ends into the locked position bencath the appropriate lugs. In jars where two cross-bars are used the lower crossbar will be locked first and the upper bar afterward.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The cover provided with the centrallyarranged fianged pivot, and the hub provided with a pivotal oifset equal in diameter to the flange of the pivot; the cross-bar having a central opening fitted on the pivotal offset; and the cross-bar forned of a wire bent upon itself to form a link open at one end and having its members bent intermediately and clasped upon the pivot between the ot-her cross-bar and the flange of the pivot.

In a f-uit-jar having the oppositely-arranged fastening-lugs and the cover provided With the central hub and pivot; the cross-bar formed of a wire bent upon itself to form a link open at one end and having its members bent intermediately to form a clasp for the pivotsubstantially as set forth.

3. The combination of the jar provided with a plurality of sets of oppositely-arranged inwardly-projecting lugs; a cover provided with a centrally-arranged hub and flanged pivot; a cross-bar provided with a central opening to fit over the pivot and upon the hub; and the cross-bar made of spring-wire formed in a link and having its members provided respectively with an intermediate bend to clasp the pivot and fitted between the other cross-bar and the flange of the pivot substantially as set forth.

l. The combination of the jar provided with a plurality of sets of oppositely-arranged inwardly-projecting lugs; a cover provided with a centrally-arranged hub and flanged pivot; a cross-bar provided with a central opening to fit over the pivot and upon the hub and provided with the upwardly-projecting lugs; and the cross-bar made of springwire formed in a link and having its members provided respectively with'an intermediate bend to clasp the pivot and fitted between the other cross-bar and the fiange of the pivot substantially as set forth.
